Terra X GRX400

This road-speed measure focuses on efficient pace on asphalt, where drag and rolling resistance matter most. Most of the story comes from wider mixed-surface tires that add some drag, aerodynamics that help it hold speed once you're rolling, and a more budget-friendly drivetrain that focuses on value. It's the combination that matters: weight, rolling resistance, and (for road) aerodynamics.

Climb score: 4.4/10. Within Road bikes, it ranks around the middle. On climbs, the lowest gear feels very easy. The easiest gear works out to about 23.8 gear inches. In its peer group, it lands around the easier ~86% for low-gear climbing. Gear inches is basically “how easy is the easiest gear”. Lower numbers help you keep your legs spinning on steep bits. This kind of low gear helps you stay smooth on long or steep climbs. Build kits can differ by size and spec level, and not every detail is published by every brand, so use this as a practical guideline.

From a gravel perspective, scoring 4.5/10 on aero, on 40mm-ish tyres, it’s tuned for mixed riding rather than pure aero focus so it feels versatile, not single-purpose. Put simply, it’s a balanced middle ground: some streamlining, but not an extreme aero setup. Tyres around 40mm are clearly aimed at comfort and control, and that usually adds some drag in the wind. In practice, it’s a balanced setup: decent in the wind without demanding big compromises elsewhere.

Comfort fit - less tuck and easier on neck and shoulders. This is an estimate; exact fit varies by spacers and rider setup.

In Road, That is why it is in the Adjustable bucket. This bike's adjustability comes down to cockpit, routing, and seat setup: A modular front-end gives more freedom to change stem length or bar width. Plus, Cable routing is on the simpler side, which helps adjustability.

This scores 6.0/10 for comfort, so it feels balanced out on the road. That’s the reason it lands as Balanced. It’s running about 40 mm tires, and wider tires let you drop pressure a touch, which smooths out rough pavement on rough lanes and gravel patches. The posture is neutral (posture 5/10), which balances comfort and responsiveness pretty well.

This looks like strong value without any tricky caveats. The value score is 1–10. Higher means better value for money; lower means the price is high for what you get. Uses MSRP as a baseline; real-world prices can be lower (discounts can change the value). Based on the spec estimate, it comes in about 14% under the typical level for similar builds. In its peer group, it tends to be better-priced than many, beating about 77% of listings. To anchor it: price €1.749 versus an estimated €2.025 for a similar build. Put simply: this is strong value for what’s included.

This bike is comfortable on gravel roads and unpaved back roads, and it still rides well on tarmac. Tires around 40 mm are well suited for gravel roads and unpaved connectors. Overall, the setup matches this surface range well.
